Two-part hair dye compositions containing polyether polyurethanes and conditiong agents

ABSTRACT

The present invention describes a two-part oxidative hair dye composition which comprises in one or both component parts at least one polyether polyurethane in combination with at least one cationic conditioning agent. The two component parts of the composition comprise a dye component composition, which includes primary intermediates and couplers, and a developing component composition, which includes an oxidizing agent, such as hydrogen peroxide. It has surprisingly been found by the present inventors that nonionic polyether polyurethane polymers and cationic conditioning agents contained in the oxidative hair dye compositions of the present invention impart and significantly enhance additional conditioning and rheological benefits to the hair. Other components commonly used in oxidative hair dye products can be added to one or both component parts of the compositions of the present invention. After mixing the two component compositions, the resulting hair dye composition mixture is thick, conveniently applied, and provides superior rheological and conditioning properties to the hair.

FIELD OF THE INVENTION

[0001] The invention relates generally to compositions and methods forpreparing stable oxidative hair dye products that result in long-lastingand true color and do not adversely affect the texture and condition ofthe hair after application. The preset invention more particularlyrelates to two-part aqueous oxidative hair dye compositions comprisingoxidation dye precursors in one of the two component parts and anoxidizing agent in the other component part. One or both of thesecomponent parts also contains one or more polyether polyurethanes andone or more conditioning agents. The compositions of the invention mayalso comprise other conventionally-used hair dye additives andcomponents.

BACKGROUND OF THE INVENTION

[0002] Oxidative hair dye colorants are essential elements in hairdyeing preparations for the permanent dyeing of human hair. The hairdyeing process is achieved, in general, by the reaction of certainprimary intermediates with certain coupling compounds in the presence ofa suitable oxidizing agent or compound, for example, hydrogen peroxide.

[0003] When oxidation dyes, such as those comprising primary dyeintermediates and couplers, are used in the dyeing of human hair, theprocedure typically involves the use of a two-part system. In general,one part can be a lotion, gel or cream formulation, which contains avariety of ingredients, including oxidation dye precursors (i.e.,primary intermediates and coupling agents). The other part is adeveloper formulation containing a suitable oxidizing agent, e.g.,hydrogen peroxide. Immediately prior to application to the hair, the twoparts are mixed to form a thickened liquid solution, for example, alotion, cream, or gel. As a consequence of the oxidizing poperties ofthe oxidizing agent, some of the natural melanin pigment of the hair maybe bleached. The oxidation dye precursors in the thickened solution(e.g., lotion or gel) penetrates into the hair, couple and are oxidizedto produce the color. Such systems generally contain a proportion oforganic solvents and surfactants and contain relatively high levels ofdye precursors to produce the desired color.

[0004] In order for procedures using permanent oxidative dyes to workproperly, a number of parameters and conditions are important toconsider in the use of these dyes in admixture with couplers in haircolor preparations for human hair. Among these are the final color andcolor intensity that are produced after application to the subject'shair; the wash fastness and the light fastness of the resulting dye; theresistance of the dye to perspiration; the type of hair being dyed,e.g., virgin hair or waved hair; the resistance of the dye to varioushair treatments, such as permanent wave, staightening, shampooing,conditioning and rubbing. In addition, the dye must have virtally noallergenicity or dermal or systemic toxicity. Ideally, the dye productis also economical and must remain stable against the above-mentionedexternal influences and against chemical agents for a suitable period oftime after application to the hair, for example, for at least four tosix weeks, and to insure a reasonable shelf life.

[0005] The use of alkyl quaternary amines as conditioning agents in hairdye formulations has been known in the art for approximately twentyyears. More recently, the use of polyquaternium compounds has provideddurable conditioning properties to hair color formulations.

[0006] Highly aqueous bases as media for dyeing hair have been employedin the art (U.S. Pat. No. 4,776,855 and RE 33786). Thickening in a highaqueous base has been accomplished by adding a polyacrylic acidderivative to the peroxide developer. As a consequence, the polyacrylicacid derivative forms an insoluble mixture at the acid pH of thedeveloper. When mixed with the alkaline dye formulation, the polyacrylicacid becomes neutralized, which leads to thickening.

[0007] Although such aqueous bases have been described for use in aconditioning hair color product (U.S. Pat. Nos. 5,376,146 and5,393,305), there is a partial incompatibility between the conditioningagents and the polyacrylic acids. Such an incompatibility results indisadvantages to the use of polyacrylic acid derivaties combined withcationic coditioning agents, for example, quaternary amines or polymers.Specically, some of the anionic polyacrylic acid complexes with thecationic quaternary amine or polymer, thus resulting in inefficientthickening and loss of conditioning effect.

[0008] The present invention solves the above-mentioned incompatibilityproblem by the use of particular nonionic polymers for thickening thetwo-part dye composition in combination with one or more cationicconditioning agents. The nonionic polymers will not complex with theconditioning agents, thereby resulting in more efficient thickening andconditioning of the product. These polymers, which are not known to havea conditioning effect on their own, have been newly-discovered by thepresent inventors to surprisingly act to enhance the conditioning effectof other conditioning agents which may be present in the product. Thenet result of the present invention is a hair color composition withexcellent rheology and superior conditioning properties and benefits fortwo-part oxidative hair dye systems.

SUMMARY OF THE INVENTION

[0009] It is an object of the present invention to provide a two-partaqueous oxidative hair dye composition, the parts of which are mixedimmediately before or at the time of use to form a final hair dyecomposition or formulation in accordance with the present invention. Thefinal composition mixture is applied to the hair. One part of thecomposition comprises a dye formulation containing one or more oxidationdye precursors, including primary intermediates and couplers. The secondpart of the composition contains a developer formulation comprising adeveloper, i.e., oxidizing compound, preferably hydrogen peroxide. Oneor both parts of the composition also comprises at least one polyetherpolyurethane, such as is described in U.S. Pat. Nos. 4,180,491,4,155,892 and 5,281,654 and at least one conditioning agent. Inaccordance with the present invention, the polyether polyurethane ispreferably nonionic and is also preferably modified by the addition ofstarch. When starch-modified polyether polyurethane is utilized, one orboth parts of the composition can contain a low HLB nonionic surfactant.Preferably, at least one part of the composition contains a low HLBnonionic surfactant. Rheology modifiers, e.g., surfactants, fattyalcohols, electrolytes, or mixtures thereof, may also be included in oneor both parts of the composition of the present invention.

[0010] Further objects and advantages afforded by the present inventionwill be apparent from the detailed description and exemplificationhereinbelow.

DETAILED DESCRIPTION OF THE INVENTION

[0011] The present invention provides a two-part oxidative hair dyecomposition (or formulation) that is mixed immediately before or at thetime of application to the hair to form the final oxidative hair dyecomposition, i.e., the final composition. It is to be understood that,as used herein, the terms composition and formulation are considered tobe interchangeable. One component of the hair dye composition of thepresent invention contains a dye solution containing a mixture ofoxidation dye precursors, and the other component contains an oxidizingagent that initiates the oxidative coupling which forms the color. Thetwo component formulations may both be thin, pourable liquids.Alternatively, either or both of the component formulations may be agel, cream, or lotion. After mixing, the resulting final compositionmixture imparts a visible amount of color to the hair and the rheologyof the resultant mixture is such that it is easily applied to hair, setsup rapidly and does not run or drip.

[0012] In accordance with the present invention, the two-partcomposition comprises a polyether polyurethane, preferably a nonionicpolyether polyurethane, which affords thickening to the composition, anda conditioning agent, preferably, a cationic conditioning agent. Inaddition, the polyether polyurethane polymers utilized in thecompositions according to the preset invention enhance the conditioningeffects and thickening properties of the resultant hair dye compositionso as to provide superior rheological and conditioning benefits to theuser. In the two-part composition, at least one or both of the dyecomponent and the developer component compositions contains a polyetherpolyurethane polymer, preferably a nonionic polyether polyurethanepolymer, and/or a conditioning agent, preferably a cationic conditioningagent.

[0013] The polyether polyurethane, as described herein, is a blockcopolymer of polyurethane and polyethylene glycol or polypropyleneglycol. A preferred polyether polyurethane for use in the compositionsof the present invention is modified by the addition of starch, whichforms a complex with the polymer, such as is commercially available fromRohm and Haas under the tradename Aculyn 46. Another useable andillustrative polyether polyurethane that is not modified with starch issold by Rohm and Haas under the tradename Aculyn 44.

[0014] In accordance with the present invention, the polyetherpolyurethane can be present in the dye component, in the developercomponent, or in both components of the composition of the invention.The polyether polyurethane polymer is generally present in the finalcomposition in an amount sufficient to impart to the compositionrheological properties required for thickened oxidative hair dyes and toenhance the hair conditioning effect of the conditioning agent. Moreparticularly, the concentration of polyether polyurethane in thecomposition is about 0.15% to about 1.0%, by weight, and preferablyabout 0.2% to about 0.5%, by weight, based on the total weight of thecomposition. Unless indicated otherwise, as used herein, reagent orcomponent amounts are in % by weight (w/w), based on the total weight ofthe composition.

[0015] The cationic conditioning agent employed in the compositions ofthe present invention can be a monoalkyl quaternary amine, such asstearyltrimonium chloride, soyatrimonium chloride or coco-ethyldimoniumethosulfate.

The cationicconditioning agent may be present in the dye component, in the developercomponent, or in both components of the composition in accordance withthe present invention. The cationic conditioning agent is present in thecomposition in an amount of about 0.1% to about 10%, preferably about0.5% to about 5%. In addition, other conditioning agents, for example,amodimethicone, can be employed in the compositions of the presentinvention.

The nonionic, low HLB surfactant may be present in the dye partof the composition, or in the developer part of the composition, or inboth. Surfactant may also be sent in the same part of the composition asthe starch-modified polyether polyurethane, or it may be included in theother part of the composition.

Example 16

[0053] As presented in Table 1, the dye lotion component compositions ofExamples 12 and 13 were each mixed with equal parts of the developercomponent composition A as set forth above. Dye lotion componentcomposition 13 was also mixed with equal parts of developer componentcomposition B as set forth above. In addition, the dye lotion componentcomposition of Example 14 was mixed with equal parts of developercomponent composition A. The resultant oxidative hair dye mixtures wereused to treat tresses of brown hair. The combability of the resultantdye mixtures on the hair was measured using an Instron Device. Theresults are presented in Table 1.

[0055] In Table 1, “12+A” represents a typical composition in accordancewith the present invention. “13+A” is an identical composition, butwithout any thickener. “13+B” is also an identical composition, exceptthat two anionic polymers are used for thickening. “14+A” is anoxidation dye composition containing the same conditioners as the otherthree compositions, but represents a conventional composition having alow water content and a high level of surfactants. All of thecompositions contain two conditioners at the same concentrations, and itis expected that all four compositions will condition hair.

[0056] It can be seen that the surfants and solvents of the conventionalcomposition (14+A) interfere greatly with conditioning. The anionicpolymeric thickener (13+B) also interferes with conditioning, but to amuch lesser degree. The data also show that the polyether polyurethanethickener of the present invention augments the conditioning so thatthis composition (12+A) is better at conditioning than is composition(13+A) which has no thickener and is therefore not useful in hair colorformulations. Thus, it is apparent that not only does the polyetherpolyurethane thickener of the present invention provide desirablerheology without interfering with conditioning, it surprisingly actuallyenhances the conditioning effect. This is wholly unexpected since thepolyether polyurethane thickener of the present invention was notheretofore known to possess any combing improvement effect.
